Deleting Metamodel Items from the Repository
Deleting metamodel items should be done very carefully, if at all. Do not delete a metamodel item if you are unsure as to whether it should be deleted.
When a metamodel item is deleted, it is completely removed from the MDS repository; there is no undo or recovery of the metamodel item.
To delete metamodel items from the repository:
1 In the Navigation Pane, click Metamodel Administration.
2 Select an application information metamodel (AIM), and then click Go.
3 From the MDS Metamodel Administration screen you can delete the following:
4 Click OK to confirm the deletion.
There may be a delay for deletion to be accomplished, depending on the number of metamodel items being deleted.
Note: The four pre-defined and loaded metamodels (ClientLoadModel, Core, DatabaseModel, and MDSMetamodel) cannot be deleted.
